The stimulated Raman effect provides an efficient means for producing coherent optical signals throughout the visible and infrared portion of the spectrum using a single laser source as exciter and either a crystal or a cell containing a gas or liquid as the target. The Raman-shifted output retains the high-intensity well-collimated monochromatic properties of the original laser. The objectives of the research program presented in the report were to investigate those aspects of the Raman effect relevant to the possibility of constructing a tunable Raman laser in which continuous tuning over tens of angstroms could be expected.
